Abstract

The effect of light elements such as B, C and N on Sm(Fe0.8Co0.2)12 alloy was investigated in detail. The highest coercivity Hc of 11.1 kOe was obtained for Sm(Fe0.8Co0.2)12-B thin fi lms with the thickness of 100 nm and B content of 11.2 at.%. From X-ray diffraction patterns, peaks from (002) and (004) of ThMn12-type phase were clearly observed for the fi lms. However, no significant improvement in magnetic properties was observed with the addition of C and N to the Sm(Fe0.8Co0.2)12 alloy, as was the case with the combined addition with B. It was confi rmed that only the addition of B contributes significantly to the improvement of magnetic properties from the result of adding light elements to this series of Sm(Fe0.8Co0.2)12 alloy.

添加轻元素制备Sm(Fe0.8Co0.2)12薄膜的结构和磁性能
详细研究了B、C、N等轻元素对Sm(Fe0.8Co0.2)12合金的影响。厚度为100 nm、B含量为11.2 at.%的Sm(Fe0.8Co0.2)12-B薄膜矫顽力Hc最高,为11.1 kOe。从x射线衍射图中可以清楚地观察到thmn12型相的(002)和(004)峰。然而,添加C和N对Sm(Fe0.8Co0.2)12合金的磁性能没有明显的改善,而与B联合添加则没有明显的改善。从该系列Sm(Fe0.8Co0.2)12合金中添加轻元素的结果可以证实,只有添加B对磁性能的改善有显著的作用。
